Answer:
2100
Step-by-step explanation:
Surface area is the area of all the sides
The area of the rectangular base is W x L = 30 x 30 = 900
Then to find the area of the triangles its
bh
A =
30 x 20
A =
600
A = 300
Since there are 4 triangle faces on a pyramid we times 300 x 4 = 1200 is the area of all the triangles
Then we add the area's
1200 + 900 = 2100
Sorry if its wrong
Answer:
A. 45%
Step-by-step explanation:
34/75=45 = 45%
The content of the square root must be greater than or equal to zero. Determine the conditions on x that make this true.
As written, you require
.. x ≥ 0
If you intend
.. √(x -1) ∈ ℝ
Then
.. x -1 ≥ 0
Solve this inequality by adding 1.
.. x ≥ 1
28:21
because the same number has to multiply both sides of the ratio. so number = 7 and:
4x 7 = 28
3 x 7 = 21
We get all these to have the same denominators for all the fractions.
2*2/9*2 = 4/18
1*2/9*2 = 2/18
1*3/6*3 = 3/18
Now we can add all the numerators.
4/18 + 2/18 + 3/18 = 9/18
Simplify our answer by dividing both numbers by 3, then by 2.
9/3 and 18/3 = 3/6= 1/2
Our final answer is 1/2
